Defy anyone to spot the marks on these cards. Only a few people in the country will know what to look for. Perhaps the best marking system used by cheats today. Excellent for an expose on gambling. Professionally marked. Sold for entertainment purposes only. Complete with instructions by Dr. X.

This deck allows you to spot all the aces, and all the 10 spot cards (10, J, Q, K)! No one else will ever know how you did it.
